Marketplace Image Validation Utility

Check a folder of listing images for dimensions, aspect ratio, file size and readability before upload.

Choose square, 4:3, 16:9 or custom-dimension validation. The utility creates CSV and readable HTML reports showing passes, review items and unreadable files. It does not upload or transmit images.

Included:

• Offline Windows interface

• Four validation modes

• Minimum width and height checks

• Maximum file-size check

• Aspect-ratio tolerance

• CSV and HTML reports

Requirements: Windows 10 or 11 with Windows PowerShell 5.1. Destination marketplace rules can change; confirm current platform requirements before upload.
